First Light (astrophotography speaking) with iOptron SmartEQ PRO. High periodic error and resultant low percentage of keepers with my sample of this mount makes unguided astrophotography problematic at 600mm FL and approx. 7 lbs in the imaging train. Photo was taken with a Canon T3i, Celestron C80ED, SmartEQ Pro with 12 unguided exposures at ISO1600 ranging from 30 to 76 secs for an integration time of 8 min 26 secs.
